3 Description
The LM614xxT-Q1 buck converters are automotivefocused
regulators providing adjustable output voltage
which can be set from 1V to 95% of expected
input voltage. These regulators operate under a wide
input voltage range of 3V to 36V and have transient
tolerance up to 42V.
The family is designed for low EMI. The device
incorporates pin selectable spread spectrum, and an
adjustable SW node rise time. Dual Random Spread
Spectrum (DRSS) frequency hopping is set to ±4%
(typical), drastically reducing peak emissions through
a combination of triangular and pseudorandom
modulation, and includes advanced techniques to
reduce output voltage ripple caused by spread
spectrum modulation.
An open-drain RESET output, with filtering and
delayed release, gives a true indication of system
status. In auto mode, the device automatically
transitions between Fixed frequency Pulse Width
Modulation (FPWM) and Pulse Frequency Modulation
(PFM) modes of operation, allowing an unloaded
current consumption of only 5μA (typical). Electrical
characteristics are specified over a junction
temperature range of –40°C to +150°C.
